(6) RWB70B Black 6.5" Marine Wakeboard Swivel Tower Speakers+Amplifier

This package combines six RWB70B 6.5" wakeboard tower speakers (three pairs), a DBM65 six-channel marine amplifier, and an RMWK4 waterproof wiring kit into a tower audio system that is ready to install. Each speaker handles 150W RMS and 250W peak through a polypropylene mica-injected cone and neodymium tweeter, and the 360-degree swivel bracket lets you aim sound toward riders or the cockpit. The DBM65 amplifier delivers 660W Dyno-Certified RMS across six channels with bridgeable outputs and a fully adjustable crossover supporting low pass, high pass, bandpass, and subsonic modes.

The amp is built for the water: conformal-coated PCB, waterproof silicone terminal covers, an aluminum heat sink, and stainless steel hardware. A PA microphone and bass remote are included, and auto-start smart turn-on powers up the amp when it senses a signal. The RMWK4 4 AWG wire kit supplies tinned-OFC RCA cables, power and ground wire, speaker cable, a fuse holder, and all terminals. Six tower speakers and a matched six-channel amp in one box mean each speaker gets its own dedicated channel, or you can bridge channels for additional power.
